Question

read the passage. then answer the question below.
rain forests in indonesia have at least 15,000 species of plants, more than any other forest in the world. these plants include sugar palms, bornean ironwood, and durian trees.
bornean orangutans spend most of their lives in trees. staying in the trees helps the orangutans avoid predators such as the saltwater crocodiles that live in the rivers below. but other predators, such as sunda clouded leopards, can climb trees to hunt orangutans.
in a rain forest in indonesia, the bornean orangutans, the saltwater crocodiles, and the rivers make up which of the following? select all that apply.
a population
part of a community
part of an ecosystem

Explanation:

1. For "a population": A population is a group of individuals of the same species in a given area. Here, we have multiple species (Bornean orangutans, saltwater crocodiles) and a non - living component (rivers), so it's not a population.
2. For "part of a community": A community consists of all the different populations (of different species) in a given area. The Bornean orangutans and saltwater crocodiles are part of the different populations in the rainforest community, and the rivers interact with these biotic components, so they are part of the community context.
3. For "part of an ecosystem": An ecosystem includes all the biotic (living) components (like Bornean orangutans, saltwater crocodiles) and abiotic (non - living) components (like rivers) in a given area. So the Bornean orangutans, saltwater crocodiles, and rivers are part of the ecosystem of the Indonesian rainforest.

Answer:

part of a community, part of an ecosystem
